I'm after any suggestions on what to use to repair this broken pipe, I've been recommended some rubber couplings and a piece of 100mm in the middle but read that these couplings aren't recommended for pressure situations. Also been recommended an extendable coupling but they're damn expensive. Would two slip couplings glued in and a new piece of 100mm do the trick? Thanks in advance Re: Advice on Plumbing 2May 24, 2020 9:14 am mattscib I put a stake through a 100mm pvc pipe (right through) Top and bottom? Can you post a photo of the hole(s) next to a rule or similar that shows the size and any cracking additional to the hole(s)? Does the pipe have a flush outlet that will drain the sub surface pipe? 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Hi SaveH2O - yeah I put a stake through the pipe which damaged top and bottom of 100mm pipe. The damaged area is about 130mm long. Not sure what you mean with flush outlet? This pipe is connected directly to the vertical down water pipe. Re: Advice on Plumbing 4May 24, 2020 12:25 pm mattscib Not sure what you mean with flush outlet? A flush outlet allows water to flush out of the wet system but they are mostly above ground and so don't drain the underground pipe but I suppose that your pipe has lost a lot of water anyway.

Fernco advise a maximum working pressure of 4.3 psi which equates to a 3 metre head. The quickest and easiest way: 1. Buy two 100mm flexible couplings. 2. Cut out a section of the existing pipe then clean and de-burr the ends. 3. Cut a new section of 100mm DWV pipe to size. 4. Slide the two couplings over the existing pipe. 5. Mark a 'stop' distance on both ends of the new pipe and then slide both couplings over the new pipe to the 'stop' line and tighten. BTW, are you still having trouble with the rainheads?

It was previously backfilled with a large rock squashing the pipe. Left it to the plumber who installed 4 x 90 degree elbows. With regards to the rain heads, we installed a gutter guard and I removed the first 10mm square screen, we haven't had issues since. Just a regular clean of the fine gauze material mat to prevent them from clogging up with leaves.
